Am I in right place?

I need some help. It’s first time to grow.

I wonder if they are growing well, I think the growth rate is slow

At this point you know a little more about it than we do.

Strain
Sprout date
medium

lights

If it is a 3 week old jack herer you are ahead of schedule.
You do have flower set so it will grow and fill out from here.
